Three lollipops are more expensive than two pencils.
Given that three erasers cost as much as 2 lollipops.
Let e denote the cost of an eraser and l denote the cost of a lollipop.
A pencil costs as much as two erasers, which implies that the cost of a pencil is two times the cost of an eraser. Therefore, the cost of a pencil is 2e.
Likewise, three erasers cost as much as 2 lollipops, which implies that the cost of an eraser is (2/3) l.
Therefore, the cost of a pencil is 4/3 times the cost of a lollipop.
Thus, the cost of two pencils is 4/3 * 2l = 8/3 l.
The cost of three lollipops is 3l.
Now, we must determine whether 8/3 l is greater than 3l or vice versa.
8/3 l = 2.67 l
Since 2.67 l < 3 l, the conclusion is that three lollipops are more expensive than two pencils.

Prove the triangles are congruent. Make sure to include all the steps of a proof.
Check the picture below.
You were trying to answer a multiple choice question on a standardized test there are six choices if you get the question are you game and play if you get a wrong you lose 1/3 point assume you can eliminate one of the six choices and you choose one of the remaining five at random as your answer what is the expected value of the number of points you get
Let's first calculate the probability of getting the question right if you eliminate one of the six choices. Since there are six options, initially you have a 1/6 chance of getting the question right. If you eliminate one of the options, you are left with five choices, so your probability of getting the question right increases to 1/5.
Now, let's calculate the expected value of the number of points you get. If you get the question right, you earn one point. If you get the question wrong, you lose 1/3 point. So, we can write the expected value as:
Expected value = Probability of getting the question right x Points for a correct answer + Probability of getting the question wrong x Points for a wrong answer
Let's plug in the values:
Expected value = (1/5) x 1 + (4/5) x (-1/3)
Expected value = 1/5 - 4/15
Expected value = -1/15
So, the expected value of the number of points you get is -1/15. This means that, on average, you can expect to lose about 0.067 points for each question you attempt.
If triangle XYZ is dilated from center C by a scale factor of 0.5 to form triangle X'Y'Z', where is the center of the dilation, point C, located? Click on coordinate plane to plot the point.
The center of dilation, point C, is located at (4, 3/2). The center of dilation, point C, is the point of intersection of the lines joining each vertex of the original triangle to the corresponding vertex of the dilated triangle.
Since triangle XYZ is dilated by a scale factor of 0.5, each point of the dilated triangle is located halfway between the corresponding point of the original triangle and the center of dilation, point C.
Therefore, to find the location of point C, we need to find the midpoint of each line segment joining the corresponding vertices of the original and dilated triangles.
Plotting the vertices of the original triangle at points X(2, 4), Y(6, 2), and Z(3, 5) on the coordinate plane, we can use the midpoint formula to find the midpoint of each segment.
Midpoint of segment XX' = (2 + 6)/2, (4 + 2)/2 = (4, 3)
Midpoint of segment YY' = (6 + 18)/2, (2 + 4)/2 = (12, 3)
Midpoint of segment ZZ' = (3 + 9/2)/2, (5 + 7/2)/2 = (15/4, 11/4)

a history of active exercise was compared between women with hip fracture and unmatched controls. active exercise in the previous two years was reported by 31% of the cases and 46% of the controls. what is the association between hip fracture and active exercise?
There is a potential association between hip fracture and active exercise, as a smaller proportion of women with hip fracture reported active exercise compared to the controls
Based on the provided information, we can say that there is a potential association between hip fracture and active exercise. The fact that a smaller proportion of women with hip fracture reported active exercise compared to the controls suggests that active exercise may have a protective effect against hip fracture.
However, it's important to note that this comparison alone does not establish a cause-and-effect relationship between active exercise and hip fracture. Other factors, such as age, bone density, and overall health status, may also play a role in the development of hip fractures.
To further evaluate the relationship between hip fracture and active exercise, additional research would be needed, including studies with larger sample sizes, more detailed information on exercise habits, and adjustments for potential confounding factors.

Write an equation in point-slope form that has a y-intercept at (0, -3) and also contains the point (4, 5).
Write your answer as an equation with numbers, letters, and symbols - no spaces.
Answer: The point-slope form of an equation of a line is: y - y1 = m(x - x1), where (x1, y1) is a point on the line and m is the slope.
We are given the y-intercept at (0, -3), which means that this point is on the line and that the line crosses the y-axis at y = -3. Therefore, the y-coordinate of the y-intercept is -3.
We are also told that the line passes through the point (4, 5), which means that this point is also on the line. Therefore, x1 = 4 and y1 = 5.
To find the slope of the line, we can use the two points (0, -3) and (4, 5):
slope = (y2 - y1) / (x2 - x1)
slope = (5 - (-3)) / (4 - 0)
slope = 8 / 4
slope = 2
Now that we have the slope and a point on the line, we can use the point-slope form to write the equation of the line:
y - y1 = m(x - x1)
y - 5 = 2(x - 4)
This is the equation of the line in point-slope form that has a y-intercept at (0, -3) and also contains the point (4, 5).

Rounding to the nearest inch, the length of side W (w) is approximately 588 inches.
Here, we have,
To find the length of side W (w) in triangle WXY, we can use the Law of Sines, which states:
a/sin(A) = b/sin(B) = c/sin(C)
where:
a, b, c are the side lengths of the triangle.
A, B, C are the opposite angles to sides a, b, c, respectively.
In this case, we have:
Side XY = y = 940 inches
Angle Y = ∠Y = 100°
Angle W = ∠W = 38°
We want to find the length of side W (w).
Using the Law of Sines:
w/sin(∠W) = y/sin(∠Y)
Now, substitute the given values:
w/sin(38°) = 940/sin(100°)
Now, solve for w:
w = (940 * sin(38°)) / sin(100°)
Using a calculator:
w ≈ (940 * 0.6157) / 0.9848
w ≈ 588.388

phone plan?
When x = 3, y = 60 + 20(3) = 120. So, we can plot the point (3, 120).
What is equation?An equation is a mathematical statement that uses symbols, numbers, and operations to show that two expressions are equal. It usually contains one or more variables, which represent unknown values that need to be solved for. Equations are used in a wide range of mathematical fields, such as algebra, geometry, calculus, and physics, to model real-world situations and solve problems. Some common examples of equations include:
Linear equation: y = mx + b
he total expenses for Myra's phone plan include the initial cost of buying the phone plus the monthly cost of the phone plan. Therefore, the total cost can be represented by the equation:
y = 60 + 20x
where y is the total cost and x is the number of months on the phone plan.
To graph this equation, we can plot a point at (0, 60) to represent the initial cost of buying the phone. Then, we can plot additional points by plugging in different values of x into the equation and finding the corresponding values of y. For example:
When x = 1, y = 60 + 20(1) = 80. So, we can plot the point (1, 80).
When x = 2, y = 60 + 20(2) = 100. So, we can plot the point (2, 100).
When x = 3, y = 60 + 20(3) = 120. So, we can plot the point (3, 120).
Connecting these points gives us a straight line, since the equation is linear.

The dimension of cone B is r = 4 and h = 9. Because the volume formula for a cone only considers the radius and height of the cone and not orientation, we know that cones B and A have the same volume.
What is volume?The area that any three-dimensional solid occupies is known as its volume. These solids can take the form of a cube, cuboid, cone, cylinder, or sphere.
Many forms have various volumes. In 3D geometry, we have examined the numerous forms and solids such as cubes, cuboids, cylinders, cones, etc., that are specified in three dimensions. We will discover how to find the volume for each of these forms.
The volume of the cone is given by:
Volume = (1/3)πr²h
For cone B:
48π = (1/3)πr² * h
144 = r² * h
Suppose the r = 4 and h = 9:
144 = 4² * 9
144 = 144
True.
The possible dimension of cone B is r = 4 and h = 9.
Because the volume formula for a cone only considers the radius and height of the cone and not its shape or orientation, we know that cones B and A have the same volume. We utilised this rule to get the potential values for cone B: any two cones with the same volume must have the same product of radius and height.

Even and odd functions are special types of functions.
Even functionf(x) = f(- x) for all values of x.Symmetric about the y- axis.Example even function: y = x²Odd functionf(–x) = –f(x) for any value of x.Symmetric about the origin.Example odd function: y = x³An even function is symmetric about the y-axis. An odd function is symmetric about the origin. As the graphed function is neither symmetric about the origin, nor symmetric about the y-axis, it is neither even nor odd.
